For the sake of accuracy: While this calls itself an interpreter, it
actually isn't. It's a compiler generating threaded code for immediate
execution upon call. It's sort-of similar to the Thompson-shell because
it relies on separate programs for providing any 'real' functionality,
including 'control constructs'.
